Industry: NAICS & SIC

North American Industry Classification System (NAICS)
In 1997, a new system
NAICS was developed to replace the 1987 SIC system. NAICS was developed to provide new comparability in statistics about business activity across the three North America countries. NAICS codes contain six numerical digits. The codes were updated in 2002 and partially revised and updated again in 2007 (see below).


Standard Industrial Classification (SIC)
SIC codes are four digit numerical codes assigned by the U.S. government to business and industry in an effort to identify the primary business activity of an establishment. The SIC classification was developed to facilitate the collection of data, and to allow for more accurate comparisons of economic and statistical data (see below).

The NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America. Federal, State, and local governments use the Economic Census data to determine the health of industries and the economy.  Plus, business owners and entrepreneurs use the data to research specific industries (nationally and locally).  The Economic Census is a KEY resource for industry and economic research.

NAICS is a system that assigns a two-digit numerical code to each industry and 3 to 6 digits to each industry sub-sector.  The larger the number, the more specific the industry. For example:

48-49 Transportation & Warehousing (over arching industry and sub-sectors)

  • 481 Air transportation
    • 4812 Nonscheduled air transportation
      • 48121 Nonscheduled air transportation
        • 481212 Nonscheduled chartered freight air transportation

        *The economic census provides a detailed portrait of the United States' economy once every five years, from the national to the local level.  The Economic Census covers most of the U.S. economy in its basic collection of establishment statistics.

Industry: SIC

NAICS logoStandard Industrial Classification (SIC)

SIC was originally developed in the 1930's to classify establishments to promote the comparability of establishment data describing various facets of the U.S. economy.

Even though NAICS was developed to replace SIC, many publishers, companies, and government agencies still use SIC.  Some of the resources you will use are categories or searchable by SIC. 

SIC is made of ten (A-J) industry divisions and each industry and sub-industry fall into one of the divisions. The ten divisions are...
